-------------------------------
Each operating system handles the inheritance of file descriptors
differently. Windows creates non-inheritable file descriptors by
default, whereas UNIX creates inheritable file descriptors by default.
Python prefers the POSIX API over the native Windows API to have a
single code base, and so it creates inheritable file descriptors.

UNIX and the POSIX API of Windows create inheritable file descriptors by
default. Python prefers the POSIX API over the native Windows API to
have a single code base and to use the same type for file descriptors,
and so it creates inheritable file descriptors.
There is one exception: ``os.pipe()`` creates non-inheritable pipes on
Windows, whereas it creates inheritable pipes on UNIX. The reason is an
